I've read Cliff's book from cover to cover many times, and it's still my favorite book. I love the quadrajet and can't stop trying to learn as much as I can on it. On page 20, at the bottom, there is a dyno sheet with a comparison between two carburetors. Please guys go read that and get back to me. Do I understand that a carefully carefully calibrated '76 APT quadrajet (supposedly the best ones) was outran by a carefully calibrated 1970 quadrajet, and that by a very significant margin ?
